Cutting Ceramic Tiles

Cutting ceramic tiles is a very critical activity and basic steps need to be followed to cut them correctly. Various types of tools and safety devices are available for this purpose. Always use a tile cutter to score the surface along the cut line. Cuts are usually along a perimeter, in a corner or around an electrical outlet.

Most saws will accommodate tiles up to 12 inches (30 cm) in size. It's always advisable to wear safety glasses when cutting tiles. Since you are grinding the tile apart, ensure that the water have sufficient time to cool everything. The cutting procedure involves snapping on the line. Where the off cut is narrow, the snapping process will be very difficult. In this case, use a pair of pliers to gradually nibble away the off cut working slowly towards the scored line. Straight ceramic tile cutters are designed to score fired clay ceramic tiles that have a thin porcelain coating on their surface (glaze). Stone, fully vitrified porcelain tiles and some types of unglazed clay tiles may not cut properly with this type of cutter. Cutting a radius or a U-shape in ceramic tiles without breakage can be a tricky business, hence use a wet saw and nippers. A wet tile saw leaves a clean, smooth edge. A tile setter needs to trim tiles at the installation site to fit the edges of a room. The saw combines a circular blade with a water pump and hose to constantly drench the cutting area with water to reduce friction and cool the surface.

However, ceramic tile is not cut well with sharp blades. The wet-tile saw doesn't overheat and uses a relatively dull blade with no serrations. It grinds a channel through the tile. A blunt, wide, non-serrated blade uses sharp sand crystals or diamond to cut instead of sharpened metal. The circular blade is fitted with a plastic hose that splashes the blade and tile surface with a steady stream of cool water.
